Answer:
$249.75
Step-by-step explanation:
135 x 0.85
114.75 + 135
It is c tell me it is right
The altitude will be the geometric mean of the lengths, so
![h=\sqrt{4 \cdot 12}=4\sqrt{3}](https://tex.z-dn.net/?f=h%3D%5Csqrt%7B4%20%5Ccdot%2012%7D%3D4%5Csqrt%7B3%7D)
. The smaller leg is the hypotenuse of a right triangle sides 4 and
![4 \sqrt{3},](https://tex.z-dn.net/?f=4%20%5Csqrt%7B3%7D%2C)
so the usual trig cliche, hypotenuse 8.
Answer: 8
Finding x.
Suzette ran = x
Suzette biked = 4x
7 = x + 4x --) 7 = 5x --) 1.4 = x
Suzette ran for 1.4 hours
Finding y.
Quickest way is to use Suzette biked = 4x and substitute the x for 1.4 to find how much she biked.
4 x 1.4 = 5.6
1.4 + 5.6 = 7 hours the total time exercising
And the mileage adds up to.
5(1.4) + 20(5.6) = 119
Answer:
35x = 155-15
